Tires: Front 255/40-19 & Rear 285/35-19 Mickey Thompson Ultra-High Performance Street Comp Tire, no spacers used.

The springs lowered the car about 1" in the front and 1.25" in the rear, ride quality is still very good.

Here is a link to the Steeda Sport Springs for a convertible http://www.steeda.com/store/steeda-m...ings-555-8220/ I did the installation in my driveway with hand tools and a spring compressor, it went very smoothly.

 

Hah I knew I wasn't familiar with that side wall or tread pattern! Those MTs are getting pretty good reviews. How do you like em?

 

I like them so far but I have not had a chance to push them yet, still need to get an alignment after lowering, I have maybe 100 miles on the now.

This is not my DD so I only drive it on weekends.

 

Gotcha. Get that alignment taken care of! Don't want to ruin em before you even get some mileage on them

 

My '08 GT's trunk was a little low over on the pass side and it showed above the tail light and along top edge against fender. There is no adjustment except at the latch and the lid is small and pretty rigid.

I fixed it by measuring the distance between the two bolts holding the right side of trunk to hinge. Got a piece of 1/8" thick aluminum, about same size, drilled two holes, inserted it and scribed around edge of hinge, removed it and further fine tuned my cuts on the bandsaw, then clean up edges and reinstalled. Looks factory, painted edge with touch up paint .... and it raised my trunk lid for a "as near perfect" match to the fender top and above the tail light.

 

I'm really interested in setting mine up like yours. Can you tell me how the ride quality is with the lowered suspension and wider tires compared to stock? Mine is a DD but I literally only drive it about 3k miles per year (I work from home).

One thing I am very concerned about it road noise with the top down, and that stupid "bouncy" look some of the lowered cars get sometimes going over the slightest bump. How does yours feel and sound going over rough pavement?

P.s. Why does it have to be aligned after lowering?

Thanks. Your car is a big inspiration for what I hope to achieve!

 

Short version is changing static height will also change toe and caster and camber settings as various parts of the suspension move through arcs in the process of said lowering .... or raising.

It only needs to be aligned after lowering if you want it to steer and handle properly and not scrub expensive rubber off the tires.

 

Steeda Springs ride almost like stock, just slightly stiffer with no bounce over bumps.

The Mickey Thompsons are quiet with no noticeable increase in road noise over the stock size tires I replaced with the top up or down.

Lowering your car changes the suspension geometry so an alignment and adjustable Panhard Bar are required.

Thank you, go for it, you won't be sorry!
